10 top-notch public swimming pools: Kastrup Sea Baths

10 top-notch swimming pools open to the public

Kastrup Sea Baths

This Copenhagen marvel is less of a swimming pool and more of a swimming area. Situated off a 100-meter-long dock extending out over the Øresund Sound in the Baltic Sea, this "architectural pearl" boasts beauty as well as functionality.

The bath's circular shape, inspired by a conch, protects swimmers from cold winds. The decks and walkways, built of saltwater-resistant azobe wood, are a perfect place for non-swimmers to take an evening stroll and catch great views of Sweden's Saltholm Island.
